To use SLM, you don't need to have Steam open in the background. This is especially useful when certain games take up more than 30 gigabytes and you don't have a decent Internet connection. The best feature, though, is the ability to duplicate content to save backup files. Steam Library Manager is a useful external tool that lets you move game installation folders and even save them on different physical drives. Steam is the main distribution platform for PC software, and although it continues to add new features to its official client, the truth is, there are still some things missing.
